Wicked and confused Bembidion

There are over 1200 known species of Bembidion.  Many of them are hard to tell apart.  They are small beetles.  Maybe for this reason some taxonomists have struggled with them, and their frustration occasionally is expressed when they name new species.  For example, there is “Bembidion confusum“, named by Roland Hayward, and “Bembidion impotens“, named by Thomas L. Casey.  In fact, there are least 42 names that have been applied to North American Bembidion that express scorn, deception, uncertainty, and dejection:

    The ‘Gratuitous Bemb’? Love it. Looks like Casey was a bit of a hater…
